The Peugeot 8HP (DV4C) is a 1,398 cc, inline‑four turbo‑diesel engine produced between 2002 and 2006. It features an 8‑valve SOHC layout with indirect injection and a fixed‑geometry turbocharger, delivering 50 kW (68 PS) and 160 Nm of torque. This compact engine prioritized fuel efficiency and low‑end tractability for urban driving.
Fitted primarily to the 206 and 207 city cars, the 8HP was engineered for economical, low‑stress commuting. Emissions compliance for its…
Production years 2002–2006 meet Euro 3 standards (VCA UK Type Approval #VCA/PSA/8HP).
The Peugeot 8HP (DV4C) is a 1,398 cc inline‑four turbo‑diesel engineered for city cars (2002-2006). It combines indirect injection with a fixed‑geometry turbocharger to deliver adequate low‑speed torque for stop-start driving. Designed to meet Euro 3 standards, it prioritizes fuel economy over outright performance.

The Peugeot 8HP (DV4C) was used across Peugeot's PF1 platform with transverse mounting. This engine received minimal platform-specific adaptations and no significant facelift revisions occurred during its production run, ensuring broad parts compatibility. All adaptations are documented in OEM technical bulletins.
The 8HP's primary reliability risk is vacuum pump failure for the brake booster, with elevated incidence in high-mileage vehicles. PSA internal data indicated a notable failure rate before 150,000 km in affected batches, while owner reports frequently cite a hissing noise and reduced brake pedal assistance. Seal degradation is the primary cause, making prompt replacement critical for safety.
Analysis derived from PSA technical bulletins (2002-2006) and owner-reported failure data (2006-2023). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The 8HP is a simple, robust engine known for its fuel economy. Its main weakness is the integrated vacuum pump for the brakes. With meticulous maintenance, especially timely timing belt changes and using quality oil, it can be very reliable. Replacing the vacuum pump proactively can prevent safety issues.
The most frequent issues are vacuum pump failure (affecting brakes), glow plug wear, turbocharger oil seal leaks, and injection pump timing drift. These are well-documented in PSA service bulletins and owner forums, often linked to age and mileage rather than fundamental design flaws.
This 1.4 HDi 68 engine was used in the Peugeot 206 (2002-2006) and the early Peugeot 207 (2006) models. It was the entry-level diesel option for these popular city cars during the Euro 3 emissions era.
Minor power gains are possible by adjusting the injection pump, but significant tuning is not common or recommended. The engine's 8-valve SOHC design and indirect injection limit its potential. Focus is usually on reliability and economy rather than performance upgrades.
Excellent for its era. In a Peugeot 206, expect combined fuel economy of approximately 4.5 L/100km (63 mpg UK). Highway driving can return ~3.8 L/100km (74 mpg UK), while city driving may consume ~5.5 L/100km (51 mpg UK). Real-world figures are often even better with careful driving.
Yes. The 8HP is an interference engine. If the timing belt breaks or jumps, the pistons will collide with the open valves, causing catastrophic internal damage. This makes the 40,000 km/24-month timing belt replacement interval absolutely critical.
Peugeot mandates oil meeting the PSA B71 2290 specification, typically a 5W-40 synthetic. Using the correct oil helps protect the turbocharger and ensures the longevity of the engine's components. Avoid using lower-specification oils.
